Understand the problem

+914:+247 +9\frac{1}{4}:+\frac{24}{7}

Step-by-step solution

Let's convert 9 and a quarter to a simple fraction:

914=9+14=9×44+14=364+14=36+14=374 9\frac{1}{4}=9+\frac{1}{4}=\frac{9\times4}{4}+\frac{1}{4}=\frac{36}{4}+\frac{1}{4}=\frac{36+1}{4}=\frac{37}{4}

Now the exercise we got is:

374:247= \frac{37}{4}:\frac{24}{7}=

Let's convert the division exercise to a multiplication exercise, and don't forget to switch the numerator and denominator in the second fraction:

374×724= \frac{37}{4}\times\frac{7}{24}=

Let's combine it into one multiplication exercise:

37×724×4=25996 \frac{37\times7}{24\times4}=\frac{259}{96}

Final Answer

25996 \frac{259}{96}

Key Points to Remember

Essential concepts to master this topic
  • Convert: Change mixed numbers to improper fractions first
  • Technique: Division becomes multiplication by reciprocal: 374×724 \frac{37}{4} \times \frac{7}{24}
  • Check: Multiply final answer by divisor to get original dividend ✓

Common Mistakes

Avoid these frequent errors
  • Dividing without converting to improper fractions
    Don't try to divide mixed numbers directly like 9¼ ÷ 24/7 = wrong answer! This creates confusion with whole and fractional parts. Always convert mixed numbers to improper fractions first: 9¼ = 37/4, then divide.

FAQ

Everything you need to know about this question

Why do I need to convert the mixed number to an improper fraction?

+

Converting 914 9\frac{1}{4} to 374 \frac{37}{4} makes division much easier! Mixed numbers have two parts (whole and fraction), but improper fractions let you work with just one fraction throughout.

How do I remember to flip the second fraction?

+

Think "division becomes multiplication by the reciprocal". When you see ÷, change it to × and flip the second fraction. So 374÷247 \frac{37}{4} ÷ \frac{24}{7} becomes 374×724 \frac{37}{4} \times \frac{7}{24} .

Can I simplify before multiplying?

+

Yes! Look for common factors to cancel. Here, you could cancel the 4 in the denominator with part of 24: 374×724=37×74×24 \frac{37}{4} \times \frac{7}{24} = \frac{37 \times 7}{4 \times 24} , but be careful with your arithmetic!

How do I check if 259/96 is correct?

+

Multiply your answer by the original divisor: 25996×247 \frac{259}{96} \times \frac{24}{7} . If you get 374 \frac{37}{4} (which equals 914 9\frac{1}{4} ), your answer is right!

Should I convert my final answer to a mixed number?

+

It depends on what the problem asks for! 25996 \frac{259}{96} is already in simplest form since 259 and 96 share no common factors. You could convert to a mixed number: 26796 2\frac{67}{96} .
